Application filed January 19, i912. serisi'lw'e'ra ar.

V To all whom it may concern:

:Be it known that we, SAMUEL P. LOVE and JOHN E. PARKER, citizens. of the United States, residing at Trenton, in the county of Grundy and State of Missouri, have invented new and usei'ullmprovements in Mold- 1 ing-Machinesbf which the following is asp oificat'ionf Ari-object of the invention is to provide a molding machine for molding structures, such astanks and the like from plastic materials.

The invention embodies more particularly a machine for use in connection with C0115. crete for moldin the sameto form'structures, such as tents and silos.

For the purpose mentioned, use is made of a main post on which is slidably mounted a .l as

frame provided with extensible members having'a mold dependingly mounted thereon and means for elevating the mentioned frameon the mentioned post, the said mold when in'initial position being adapted to receive a quantity of plastic-material, the said mold being then elevated a distance on the said post to receive a second batch of plastic material, after which the mold is. againraised a distance on the post so that the mold in being elevated each time to receive a new batch of'material acts as a-continuous mold to mold theplastic material the form ofthe Reference is to be had to the accompanya; ing drawings constituting a part of th s specification, in which similar characters of reference denote corresponding parts in all the views, and in which-- Figure 1 is a side elevation of our device showing the same in operative position. Fig. 2 is a vertical sectional View taken on the line 22 in Fig. 1, Fig. 3 is a horizontal sectional view taken on the line 33 in Fig. 1, looking in the direction of the arrow. Fig. 4 is an enlarged transverse sectional view of the center post, showing the sleeve of the frame encircling the same.

Referring more particularly to the views, we provide a center post 10 consisting of connected L-shaped rods 11, the mentioned L-shaped rods bein' secured by rivets 12 and the lower end of t e post being adapted to be received in the ground or in a concrete base 13 as shown in Fi 2. Slidably mounted on the post 10 is a 5 ame l4 consistingof a circular sleeve 15, formed of connected sec- .jsections, the inner mold connectedpto the tions 16 and secured to the upperend ofithe sleeve 15 and extending downwardly therefrom are supporting rods 17 having their lower ends 18 bifurcatedand secured to radially extending guide rods 19,

suitable braces 20 being'secured to the lower end of the sleeve 15 and to the guide rods,

, outwardly and 19 to support the same in" horizontal'position.

hers 23are hflads 24 provided with horizontal openings 25 throu h which a'reremov ably extended boltsj26 tions 27 to the heads- 24, two niold sections being preferably providedjon each head and or securing mold sectermed innermoldsections andouter mold Secured to the guide rods .19. are guides 21 and mounted to slide on the guide? rods 19 andretained thereon 121 are extensible rods 22. Link members23 are mounted on the outer ends of the rods 22 1 and dependingly mounted on the link memby. the guides-.3

sections. being spaced from the outer mold sections, the. ends Of the rear mold sectionsbeing connected to the.

ends .of adjacentinner mold sect-ions by flanges 28 provided with suitable boltsand the ends of the outer mold sections being bolts to form a circular mold 30. Secured to the lower end of the sleeve '15 are rods 31 and secured to the lower ends of the inner mold-sections are similar rods 32, the free ends of adjacent outer mold sections'by flanges 29provided with suitable ends of the rods 31 and 32 being threaded .for engagement with turn buckles 33, thus permitting an adjustment of the rods 31 and 32, the mentioned adjustment being coincident with the extensibility of the rods 22.

Although we desire to employ any convenient mechanism for elevating the frame 14 on the main post 10, for the purpose of fully describing the operation of our device we have shown aparticular method of elevating the frame and in which, we employ a cable34 having an end thereof secured to the frame 14-, the mentioned cable being then passed over a pulle 35 mounted on the up per end of the post 10 with the other end of the cable secured to a Windlass 36, operable by means of a crank 37 and mounted on the frame 14, guy ropes 88 being secured to the upper end of the post 10 and to stakes secured in the ground for the purpose of retaining the post in vertical position.

Now assuming that the extensible rods 22 have been adjusted on the guide'rods 19 to v i post 1.0

20 mold sections.

prmperly support the mold sections 27, when the frame 14L- is in its lowermost position, with the lower ends of the mold sections touching the ground or a suitable base, a

batch of concrete or the like is poured into the mold 330 between the inner and outer mold sections, after which the batch of concrete is properly taniped. The crank 37 is then actuated to operate the Windlass 36 and elevate the frame 14 on the post 10 so that the lower ends of the mold sections will slightly-overlap the finished portion ofthe structure, after which a new batch of concrete is poured between the inner and outer 15 mold sections and tanrlped, thus forming anposition being the upper end of the desired concrete structure. By employing mold sec- 'tions or various sizes and adjusting the extensible rods 22 and rods 31, 32 in accordance to the sizes of the mold sections, con- 3 crete structures of greater or less diameters can be conveniently molded with the device described it being understood that the mold I sections can be removed from engagement with the heads 24 by removing the bolts 26 from the openings 25 in the heads 2%. Having thus fully described the invention,

what we claim as new, is

1; In amolding machine, the combination with a post, of a sleeve carried thereby, radial guide rods extended from the said 40 sleeve, supporting rods on the sleeve and con- 'nected to theguide rods to support the same in horizohtal position, guides on the said guide rods, extensible rods movable inthe said guides, link members on the saidiezb tensible rods, heads supported by the said linkmembers, and connected mold sect-ions mounted to depend from the said head.

2. In a molding machine, the combination with v a post, of a sleeve carried thereby, guide rods extending from the said sleeve and movable therewith, bifurcated rods connected to the sleeve and the said guide rods to support the same in horizontal position, extensible rods mounted to slide on the said guide rods, link members on the said extensi-x ble rods, heads supported by the said link members, and connected mold sections mounted to depend from the said heads.

fl n testimony whereof we afiix our signatures in presence of two witnesses,
